Programming / creating UTF-8 text file
« on: March 10, 2024, 05:19:57 AM »
Hello. I'm trying to get our product data into a CSV-file and use this to import our data into a webshop. So I OPEN LOCK (7)"datafile.csv" and then I PRINT the requried data into that csv-file.
That works fine. I can open the file with Windows Editor and everything looks good. But when I import the file into the webshop, the accented characters look weird.So the problem is the codepage . The shop requires UTF-8 file format. And the file my little program has created is ANSI. So my questions is: How can I create UTF-8 text files (no BOM) or would I need to use a CLI tool to convert the file from ANSI to UTF-8?
Best regards

Thin Client/WindX / Windows 11 and WindX: switching window focus after NET USE
« on: July 09, 2023, 04:20:44 PM »
Hello
We are using WindX on our windows clients. We run some programs that can be as old as 40 years and have been written on MAI business basic. So in those days we used OPEN (7) "LP" and then Print (7)" bla bla bla" with printers directly attached to the computer using ESC-sequences for character-based printing.
When we made the move to PxPlus we wrote a little "choose your printer" program where you can choose a printer and then it does INVOKE WAIT "[lcl]net use lpt1: \\192.168.xxxx\printershare" so the LPT1 was re-directed by windows to the appropriate printer share. Then you can still print to LP and the data flow is redirected to the printer share.
We have multiple WindX windows open on a client so we can work in several of our programs the same time. This runs great up until Windows 10. But when a client runs on Windows 11, after the NET USE command the focus of the window changes to another instance of WindX.
Imagine you have two WindX windows open and in the first one you do the NET USE to redirect LPT1 somewhere. Windows will quickly open a command line window, execute the NET USE command and close its window again. But on Windows 11 the focus is then set on the wrong WindX window. When you type on your keyboard, the input will be in the second WindX window. You have to Alt-TAB or take your mouse curser and click the first WindX window to continue. Which is very annoying. Especially as up until Windows 10 I didn't experience this behaviour on any client.
So I think this is not a PxPlus bug. It's rather based on some changes of Windows 11 so that when the command line window opens, Windows doesn't rememenber which window was active before that.
So I wonder if there is a way I can instruct PxPlus to do the NET USE command in an "invisible" command line window so that no command line window (looks like DOS window) is opened and therefore the focus stays on the active WindX window.
Or could this still be solved in an update of WindX?
Thanks already for your ideas.

Programming / Record Expansion Factor
« on: September 26, 2022, 11:45:07 AM »
Hello
Could someone please explain to me what Record Expansion factor is? See for example the attached screenshot. It's a variable length record of 400. I see a 10% record expansion factor. What does it mean and how can I use this? Furthermore I see that the record size range is indicated 400-2024. Now I'm completely confused... Can someone please enlighten me?
The reason I'm asking is that I have not enough space in this file. I would like to write records with a length of 430 characters instead of 400. So now I'm not sure if I can use 440 anyway without errors (those 10%) or as much as 2024. Or do I have to change the Max record size?
Of course I have checked the documentation but there is no explanation.
Thanks a lot in advance for your help and explanations.

Programming / QR Code
« on: October 27, 2021, 02:25:17 AM »
Hello
From this topic: https://forum1.pvxplus.com/index.php?topic=205.0 I have learned how to create QR-Codes. And it seems to work fine. However, I found out that there are different levels of error correction in QR codes. Higher levels create bigger QR codes, but they become safer to read, even if you for example place a little logo on top of the QR code.
Is there any plan to further develop the *tools/makeqrcode tool to add more options like error-correction-level, size of PNG file, etc.?
